Mouth rinses and tooth sensitivity treatment compositions
View Patent ↗The present invention relates to tooth sensitivity treatment compositions, including mouth rinses, comprising C 2 -C 5 diacid, triacid or tetraacid salts and a tastemasking agent(s). Methods for using the compositions are also disclosed.
1. A composition for treating sensitive teeth comprising:
i. from about 0.1% to about 3% of at least one potassium salt of a C2-C5 diacid, triacid, or tetraacid;
ii. at least one vanilla flavor extract;
iii. from about 0.001% to about 0.25% of menthol or a derivative thereof;
iv. at least one orally acceptable solvent; and
v. from about 0.01% to about 2% of an alkyl sulfate surfactant;
wherein the composition is a toothpaste, dentifrice, tooth gel, subgingival gel, denture care product, mouth spray, lozenge or chewable tablet, and comprises up to 1% v/v of the total composition of C2-C4 monohydric alcohols.
2. The compositions according to claim 1 wherein the alkyl sulfate surfactant is an alkyl sulfate surfactant having an even numbered C8 to C18 chain length.
3. The compositions according to claim 2 wherein the alkyl sulfate surfactant is selected from the group consisting of sodium lauryl sulfate, hexadecyl sulfate and mixtures thereof.
4. The composition according to claim 1 further comprising from about 0.01% to about 2% of an additional surfactant.
5. The composition according to claim 4 wherein the additional surfactant is a taurate.
6. The composition according to claim 1 wherein the vanilla flavor extract is selected from the group consisting of vanillin, ethyl vanillin, heliotropine, propenyl guaethol, vanilla extracts, veratraldehyde, 4-cis-heptenal, diacetyl, butyl lactate, ethyl lactate, methyl-para-tert-butyl phenyl acetate, gamma and delta hexalactone and heptalactone, benzodihydropyrone, butter starter distillate, delta tetradecalactone, butyraldehyde, and mixtures thereof
7. The composition according to claim 6 wherein the vanilla flavor extract is ethyl vanillin.
8. The composition according to claim 1 wherein the composition contains from about 0.001% to about 0.12% of the vanilla flavor extract.
9. The composition according to claim 1 wherein the composition contains from about 0.01% to about 0.15% the menthol or a derivative thereof.
10. The composition according to claim 1 wherein the menthol or derivative thereof is menthol.
11. The composition of claim 1 wherein said at least one potassium salt of a C2-C5 diacid, triacid, or tetraacid is a potassium salt of oxalic acid, citric acid, propane-1,2,3,tricarboxylic acid, or a mixture thereof
12. The composition of claim 11 comprising from about 1 to about 2% of said potassium salt of oxalic acid, citric acid, propane-1,2,3,tricarboxylic acid, or a mixture thereof
13. The composition of claim 12 wherein the vanilla flavor extract is selected from the group consisting of vanillin, ethyl vanillin, heliotropine, propenyl guaethol, vanilla extracts, veratraldehyde, 4-cis-heptenal, diacetyl, butyl lactate, ethyl lactate, methyl-para-tert-butyl phenyl acetate, gamma and delta hexalactone and heptalactone, benzodihydropyrone, butter starter distillate, delta tetradecalactone, butyraldehyde, and mixtures thereof
14. The composition according to claim 13 wherein the composition contains from about 0.001% to about 0.12% of the vanilla flavor extract.
15. The composition according to claim 14 wherein the composition contains from about 0.01% to about 0.15% the menthol or a derivative thereof.
16. The composition of claim 15 wherein said at least one C2-C5 diacid, triacid, or tetraacid salt is potassium oxalate.
17. The composition according to claim 16 wherein the vanilla flavor extract is ethyl vanillin.
18. The composition according to claim 17 wherein the menthol or derivative thereof is menthol.
19. The composition according to claim 18 wherein the alkyl sulfate surfactant is sodium lauryl sulfate.
20. The composition according to claim 19 wherein the composition is free of C2-C4 monohydric alcohols.
